1.	An athlete runs 300 metres up a hill at a steady speed of 3.0 m / s. She then immediately runs the same distance down the hill at a steady speed of 6.0 m / s. What is her average speed for the 600 metre run? A 2.0 m / s B 3.0 m / s C 4.0 m / s D 4.5 m / s
Answer» 4 m/sExplanation:formula used=> 2v₁v₂/v₁+v₂procedure:-total distance=600 mv₁=3 m/sv₂=6 m/susing the formula,=2×3×6/3+6=36/9=4 m/stherefore, her average SPEED will be 4 m/shope it helps and pls MARK as brainliest:)
